Changes since v4:
- Rebased to linux-3.8-rc1.

Changes since v3:
- Includes changes suggested by Tomasz Figa [off-list ref]

This patch series migrates the Samsung Exynos4 SoC clock code to adopt

the

common clock framework. The use of Samsung specific clock structures has
been removed and all board support code has been updated. imx-style of
clock registration and lookup has been adopted for device tree based
exynos4 platforms.

I'd prefer to see if exynos4 and 5 were kept common here, and both
transitioned
at the same time. Especially since there are no legacy boards for exynos5,

it

would mean you could have a very clean transition there. What's the plan

to

follow up with 5?

Yeah, I'm working on EXYNOS5250 common clk stuff and Thomas is working on
EXYNOS5440. So I think, we can move on exynos4 and 5 both common clk at the
same time. Note, EXYNOS5 common clk stuff will be submitted in the beginning
of Jan.

As per the other reply, that sounds good -- it doesn't make sense to merge one
without the other but it sounds like maybe they can both be ready in time for
3.9.

What are the plans to remove legacy board files on exynos4 at this time
and switch them to DT-only? You could do it gradually like Stephen Warren
did on Tegra, with hooks that call out to some of the legacy code, but
configure the board through device tree and do away with the classic
machine descriptors, etc.

I had a plan to remove non-DT support on EXYNOS4 for v3.10, but if possible,
I will try to do it for v3.9. If any updates, let you know.

There's no hurry, 3.10 is ok as a target as long as it's taking place. The main
reason for why I was asking was that there was still some legacy board file
updates posted, and that I hadn't seen much patches lately that made it obvious
that there was an effort in that direction. 3.10 sounds like a good target.

Happy New Year!

Thanks, you too.
